Abstract

An apparatus, system, and method are disclosed for improving engine development. Engine development is improved by equipping a vehicle with a data logger to collect engine performance data, automatically retrieving the data via a secure local wireless network, uploading the data to an enterprise communication server via a secure wide area network, and analyzing the data. The vehicles and vehicle depot may be equipped with WAPs. The wide area network may comprise a VPN over the internet. In certain embodiments, the secure local wireless network is only accessible to wireless devices with registered MAC addresses.

Claims

1. A method for improving engine development, the method comprising:

equipping a vehicle associated with a vehicle depot with a data logger, the data logger configured to selectively collect data directly from first sensor related to engine performance, the vehicle depot being equipped with a vehicle server;

driving the vehicle to collect engine performance data;

automatically retrieving the engine performance data from the vehicle to the vehicle server via a secure local wireless network proximate to the vehicle depot;

uploading the engine performance data to an enterprise communication server via a secure wide area network;

analyzing the engine performance data to improve engine development; and

updating the data logger, wherein updating comprises instructing the data logger to collect new performance data by collecting data directly from a second sensor related to engine performance.

2. The method of claim 1, further comprising equipping the vehicle or vehicle depot with a WAP to extend the coverage of the secure local wireless network.

3. The method of claim 1, wherein the vehicle server and data logger operate as FTP servers.

4. The method of claim 1, wherein the secure wide area network operates as a VPN over the internet.

5. The method of claim 1, further comprising formatting the engine performance data into a report.

6. The method of claim 1, further comprising monitoring engine performance data in real-time.

7. The method of claim 1, wherein the data logger is updated via the secure local wireless network.

8. The method of claim 1, wherein the vehicle server is updated via the secure wide area network.

9. The method of claim 1, further comprising requiring a registered MAC address to access the secure local wireless network.

10. A system for improving engine development, the system comprising:

a plurality of vehicles associated with a vehicle depot, each vehicle being equipped with a data logger, the data logger configured to collect data from at least one sensor related to engine performance;

a vehicle server proximate the vehicle depot, the vehicle server configured to automatically retrieve engine performance data from the vehicles via a secure local wireless network; and

the vehicle server further configured to upload the engine performance data to an enterprise communication server for analysis via a secure wide area network;

wherein the data logger of each vehicle is updatable via the vehicle server, enterprise communication server, and another of the plurality of vehicles.

11. The system of claim 10 wherein the vehicle or vehicle depot is equipped with a WAP to extend the coverage of the secure local wireless network.

12. The system of claim 10 wherein the vehicle server and data logger are configured to operate as a FTP servers.

13. The system of claim 10 wherein the secure wide area network operates as a VPN over the internet.

14. The system of claim 10 wherein the performance data is formatted into a report.

15. The system of claim 10 wherein the data logger is further configured to provide real-time engine performance data.

16. The system of claim 10 wherein the data logger is updated via the secure wireless network.

17. The system of claim 10 wherein the vehicle server is updated via the secure wide area network.

18. The system of claim 10 wherein the vehicle communicates directly with another vehicle via the secure local wireless network.

19. The system of claim 10 wherein the data logger or vehicle computer is configured to provide a registered MAC address before accessing the secure local wireless network.

20. An apparatus for improving engine development, the apparatus comprising:

a local wireless network comprising a vehicle server located at a vehicle depot, the vehicle server being configured to wirelessly communicate with wireless communication devices proximate to the vehicle depot;

a security module configured to verify a wireless MAC address of a vehicle equipped with a wireless communication device;

an automatic retrieval module configured to automatically retrieve engine performance data from the vehicle to the vehicle server via the wireless communication device; and

an automatic upload module configured to automatically upload the engine performance data from the vehicle server to an enterprise communication server remote from the vehicle depot via a secure wide area network;

wherein a user remote from the vehicle depot can view the performance data retrieved from the vehicle in real time via the enterprise communication server.

21. The apparatus of claim 20 wherein the local wireless network comprises at least one WAP.

22. The apparatus of claim 20 further comprising an update module configure to update the data logger or apply updates from the wide area network.

23. The apparatus of claim 20 wherein the security module is further configured to encrypt or decrypt a data stream.

24. The apparatus of claim 20 wherein the secure wide area network operates as a VPN over the internet.

25. A machine readable medium comprising operations for improving engine development, the operations comprising:

automatically retrieving engine performance data from a vehicle associated with and proximate to a vehicle depot via a secure local wireless network;

automatically uploading the retrieved engine performance data to a vehicle server proximate the vehicle depot;

automatically uploading the engine performance data from the vehicle server to an enterprise communication server remote from the vehicle depot via a secure wide area network; and

analyzing the engine performance data in real time via the enterprise communication server to improve engine development.
